• Support front and rear filters - The lens also comes with a rear filter holder, allowing photographers the freedom to combine multiple filters to suit a huge variety of shooting situations for near-unlimited creative potential at an ultra-wide viewing angle.
• Designed for perfect results even in the most demanding conditions - When the MFL switch is set to “LOCK”, the focus ring operation will be disabled.
  This is to prevent the focus ring from accidentally being moved, which would cause out-of-focus images.
• Highest optical performance on a new level - With 17 glass elements arranged in 15 groups, including two SLD, three aspherical glass elements, and the largest class double-sided aspherical glass element in SIGMA’s history, the lens is rigorously suppressed various optical aberrations such as sagittal coma flare or image distortion to produce highly-detailed images with exceptional sharpness and accuracy from the center to the furthest corners, allowing photographers to make use of the entire field of view afforded by its ultra-wide viewing angle.
• Aperture ring - It is designed to help users work intuitively.
• Aperture ring click switch - Mounted with a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.
• Aperture ring lock switch - It is used to prevent from unintended movement of the aperture ring during shooting.
• Lens heater retainer - The lens heater is used to prevent internal condensation as the temperature drops on longer night shoots and will stay securely attached to the barrel without protruding into the image and causing unsightly vignetting.
• Superb build quality and usability with uncompromising attention to detail - Its dust- and splash-resistant structure and the water- and oil-repellent coating on the front glass element makes the lens safe to use during longer outdoor shoots, especially during the night.
• Dust and Splash Resistant Structure - This lens features a highly effective dust and splash-resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
• Super Multi-Layer Coating - In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA’s Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast
• Inner focus system - To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
• Designed to minimize flare and ghosting
• Every single lens is evaluated with SIGMA’s proprietary MTF measuring system
• 11-blade rounded diaphragm
• High-precision, durable brass bayonet mount
